SDI Sets the Standard for Custom Products

SDI the 'S' is for steel.

If it's made of steel and used as a door or frame, chances are you can find it in the portfolio of the Steel Door Institute's members.

Often thought of as manufacturers of 'standard' steel doors and frames, the SDI portfolio includes a wide variety of specialty and custom products ranging from high-performance acoustic solutions, bullet resistant, blast rated and tornado shelter certified openings.

Ensure your custom products are built to last by specifying that they "shall be provided by an SDI member company." After all, they are the only manufacturers that have been audited to ensure they meet or exceed SDI standards.
